[During electoral campaigns in India, candidates and parties often post publicity posters (“flex signs”) — a method which Maoists have apparently also adopted to promote their revolutionary program and slogans, to the distress of State police and their electoral masters and bourgeois media. — Frontlines ed.]
Suspected Maoists put up flex boards in Attappady, Kerala

Electioneering on flex boards. Pictures of the Maoist advocate’s posters are not published in the Indian bourgeois press.
The police have stepped up vigil in Attappady region following the appearance of flex boards allegedly installed by the banned Maoist outfit to exhort the working class to prepare for an ‘armed battle’ against ‘ruling elites.’
While most of the flex boards were seen in Kallamala region of western Attappady on Friday morning, a few were installed at Poonchola and Pambbanthode villages close to Mannarkkad. The boards claimed their ownership to a special regional committee of the CPI(Maoist) Western Ghats unit.
The boards said the organisation was observing the 10th anniversary of its armed resistance and sought cooperation of the general public in strengthening the party base in the three southern States. It wanted strong public vigilance against concerted efforts of the ruling class to plunder water, land, forests, and natural resources.
